Series 99 modules for sockets Plug-in modules are convenient add-on devices for relays which offer LED indication (for ease of viewing relay status from a distance), diode protection, RC circuits, bypass and timing facilities for all socket-mounted plug-in relays. The modules simply plug into specific sockets to enhance the relays functionality. Depending on module selected, they can provide; Suppression of coil back emf on switch-off LED indication to show when the coil in energized Protection against reverse polarity applied across the coil terminals By-pass of troublesome leakage currents in the coil circuit LED + varistor module LED + varistor modules are used for AC and DC coils, reverse voltage peaks of the relay coil are limited by the varistor to approximately 2.5 times the nominal voltage of the supply. Insignificant increase in release times. VOLTAGE 28 – 60 VAC/DC DESCRIPTION Plug-in led + varistor module LED COLOUR Green
